Following the 7.1.5 Classes Q&A, Blizzard has pushed a small PTR build with some class changes. This follows a large build from Monday with new talents, Nighthold loot rebalancing, and micro-holiday testing.

Blizzard also buffed several specs via "auras" which allows many spells in a spec to be changed quickly at once. These affected spells do not show up via normal datamining but we have added spec changes and the related spells to our spell diff. For example, the traditional spell diff only shows a nerf to Voidform for Shadow Priests, but the aura Shadow Priest buffed many other Shadow Priest abilities by 25%.

Micro-holidays are new types of celebrations coming in Patch 7.1.5; each one will last for only a few days and pay tribute to a different part of Azeroth's culture. Over the next few weeks, a different one will be up to test each day on the PTR!

Call of the Scarab (January 21 - 23): "On this date, the Scarab Gong was rung, opening the gates of Ahn'Qiraj. Represent your faction by gathering supplies or by slaying Twilight and Qiraji forces. The winning faction gets to fly their banner next to the Scarab Gong for the rest of the year!"

The event will pit the Alliance and Horde against each other to earn the most credit (Horde War Effort Credit): whoever wins can fly their faction flag in Silithus for a year.
